Side tear tabless T-shirt style bag pack

ABSTRACT

A t-shirt style grocery or merchandise bag pack includes a plurality of plastic bags, each having a pair of bag handles and a central tab located above the bag mouth. The bag pack is suspended from a dispensing rack by openings through the bag handles and a hanging aperture located in the central tab. The tab is designed to rupture at the hanging aperture when the bag is dispensed from the rack. The tab may have a flattened top and a pair of opposed lateral sides or it may have a rounded top. The weakened area may take the form of a cut or a notch. These weakened areas may begin at the hanging aperture or one of the lateral sides of the flattened top tab or at a point below the top most point of the rounded tab. The weakened area may also be perforation or a single opening.

FIELD OF INVENTION

The invention pertains to plastic grocery, produce and merchandise bags.More particularly, the invention relates to T-shirt style handle bagsmanufactured in registered stacks for dispensing from racks. The bagsare dispensed without leaving a torn tab portion on the dispenser.

BACKGROUND OF THE INVENTION

T-shirt style bags were developed to provide a strong, low-cost, highcapacity bag for groceries or merchandise that incorporates strong,integral handles. This is accomplished by creating a gussetedpolyethylene tube, sealing it at both ends and cutting out a “mouthsection.” The result is a bag that includes a pair of strong handlesformed from the side gussets and the bag's upper seam. While such bagsare very useful for transporting heavy loads, they can be difficult toload as they lack the means to stand upright while empty, as does asquare-bottomed paper bag.

For this reason, racks have been developed to hold and dispenseregistered packs of t-shirt style bags. In order to be dispensable fromsuch racks, the bag packs typically have a pair of apertures through thebag handles to fit on side arms of the dispenser and a central tab. Thecentral tab includes an opening or slit designed to fit over a hook orprotrusion at the center of the dispenser. Early designs for T-shirt bagpacks included a central tab designed to be torn from the bag upondispensing. Such systems, while effective, required periodic removal ofthe torn off tabs from the dispensing rack. More modern designs, knownas tables T-shirt bags, have incorporated a weakened area or perforationline connecting the aperture or slit used for suspending the bag packfrom the dispenser's hook, to the top edge of the tab. Thus, when thebag is pulled from the dispensing rack, the weakened area will break andthe tab will remain with the bag. Various designs for such tablessystems have been developed.

U.S. Pat. No. 5,979,655, issued to Tseng et al., discloses a plastic bagstack with special tab opening. A tab is mounted on the central retainerof a conventional rack. A slot or opening is provided by means of a cutcomprising a transverse base line that extends part way between the sideedges of the projection or tab and terminates at each end in an upwardlyand backwardly extending curve respectively. The curve extends as a veryshort segment and then continues as a reverse curve upwardly toward theupper edge of the tab leaving a small tear space between the curveterminus and upper edge. Any force applied at the opening of the tabwill rupture the area, thereby permitting removal of the tab from therack retainer element with the remainder of the bag.

U.S. Pat. No. 6,446,810, issued to Huang et al., is directed to atabless self-opening bag pack. The tab portion has a curved apertureslit that is used to suspend the pack of bags on a rack. Each curvedaperture slit has a main cut section that is substantially parallel withthe bottom edges, a first curved cut section coupled to one end of themain cut section, and a second curved cut section coupled to an oppositeend of the main cut section. The slit extends from an end of the firstcurved section to the top edge of the tab and is made when the bag isopened up on the bagging rack.

U.S. Pat. No. 5,881,882, issued to Fletcher et al., discloses a plasticbag pack adapted to leave no residue on a supporting rack. The bagsinclude a detaching central tab having an aperture for mounting the tabson a tab retaining device of the rack. Each of the bags of the packfurther includes a means to propagate a controlled tear from the tabmounting aperture to the open mouth for detaching the tab from the racktab retaining device. This tear propagating means is in the form of aV-shaped cut-out formed in and extending downwardly from the top of thecentral tab and a nick formed at the apex of the V-shaped cut-out andextending downwardly there from toward the tab mounting aperture. Whenstresses are placed on the detaching central tab, the stresses areconcentrated by the V-shaped cut-out into the nick to propagate a teardown through the wall of the detaching central tab to the aperture.

U.S. Pat. No. 5,346,310, issued to Nguyen, is directed to athermoplastic bag system. The bag has a mouth from which emanates a tab.Situated at an angled, lateral position relative to the upper edge ofthe bulbous portion of tab is the tab support slit having first andsecond ends. The tab is shown in more detail and includes a slit havingfirst and second ends, the first end being formed near the first bulboustab extension and running generally toward the first, short neck edge,then generally leveling horizontally in the medial area of said slit,then running downward along path and curving back towards generally thefirst bulbous tab extension before terminating in an end. The userapplies light pressure to the face of the tab and the slit ruptures atits higher, first end, tearing to the outer edge of the tab at rupturezone, releasing the tab from the rack.

U.S. Pat. No. 6,269,950, issued to Nguyen discloses a tab-freethermoplastic T-shirt bag system. Emanating from the bag mouth is araised area with a support cut having first and second ends. Relative tothe support cut is a laterally situated dispense cut having first andsecond ends. The application of light pressure to a medial edge of thesupport cut causes a rupture at the space between the edge and thesecond, bottom tip of the dispense cut, the rupture communicating withthe dispense cut, releasing the bag from the support tab.

It is an objective of the present invention to provide a T-shirt stylegrocery or merchandise bag that will not leave any portion of the bagtab on a dispensing rack. It is a further objective to provide such atabless bag that can be easily and reliably manufactured and that can bestored in registered alignment for ease in placing into a dispensingrack. It is a still further objective of the invention to provide atabless bag stack that includes a weakened area permitting the tab torupture at a point below the top of the tab. Finally, it is an objectiveto provide a tabless T-shirt style bag incorporating self-openingfeatures.

While some of the objectives of the present invention are disclosed inthe prior art, none of the inventions found include all of therequirements identified.
